The Omeka dropbox plugin has been released for the latest version of Omeka, 0.10. It allows Omeka users to ‘batch upload’ a large quantity of files at one time, and creates unique items in the archive for each file. Additionally, it allows you to associate numerous files with pre-existing items in edit mode.
I encourage you to give it a try. Download the latest version of Dropbox, and check out other plugins in on our plugins add-ons page.
